| 910 | 2016-12-2 | Loess Kindchen | Loess Hills Kindchen "Children of the Loess" Formed as rainfall or snowmelt percolates through the loess soil, it dissolves the calcium in the soil. When the calcium rich water reaches a nucleus the calcium carbonate precipitates out, forming a concretion around the nucleus. These concretions commonly are irregularly shaped nodules of calcium carbonate, many of which resemble tiny dolls, hence thier name. |
